ELECTRIC CURLING-IRON HEATER.

Specification of Letters Patent.

Application filed September 30, 1909.

Patented Mar. 1, 1916).

Serial No. 520,362.

T 0 all whom it may concern:

Be it known that I, CATHORINE P. Han- MON, a citizen of the UnitedStates, residing at Evanston, county of Cook, and State of Illinois,have invented certain new and useful Improvements in ElectricCurling-Iron Heaters, of which the following is a specification.

My invention relates to improvements in electric curling-iron heaters,and the objects of the invention are to provide an electrically heatedcurling iron heater which can be readily attached to an electric lightsocket, and to provide means for the reception of different sizes ofcurling-irons, a further object being to dispose said last named meansso that the curling-iron will remain in the heater by its own gravity.

A further object is to provide a suitable heat insulating means orcovering for the shell of the heater to prevent burning of the hands ofthe person using the device. And a further object is to provide a deviceof the character described which shall be simple of construction,inexpensive of manufacture, and efiicient in operation.

Other objects will appear hereinafter.

lVith these objects in view my invention consists in the novelconstruction and arrangement of parts which will be hereinafter fullydescribed and more particularly pointed out in the appended claims.

My invention will be best understood by reference to the accompanyingdrawing forming a part of this specification, and in which,

Figure 1 is a side elevation of my improved curling-iron heater in itspreferred form, Fig. 2, is a front elevation thereof, and Fig. 3 is avertical longitudinal section.

Referring now to the drawings, 1 designates the shell of the heaterwhich is preferably oblate spheroidal or egg-shaped in form the majoraxis of which is in a horizontal plane when in position for use. Acovering 2 of asbestos or other suitable heat insulating material isprovided on the shell 1 which not only serves to prevent the radiationof heat but to prevent the burning of ones hands should the heater betouched accidentally. Tubes 3 and 4 are obliquely arranged in the shell1 and pass each other as shown, the length of the tubes being sufficientto receive the operative portion of the tongs of the curling-iron 1. Thetubes are of different sizes so that if one tube is too small to receivea curling-iron, the other may be used, the heater thus accommodatinglarge and small curling-irons. It will be readily seen that it is ofimportance to have as little clearance in the tubes as possible sincewith a close fit heat will be transmitted to the curling-iron with aminimum of air resistance. The oblique disposition or inclination of thetubes to the plane of the major axis of the shell is to assure that thecurling-iron will remain in place by its own gravity. The resistancecoil 4: which connects with. the plug 5 may be of any well known form ofconstruction.

The shape of the shell is of importance since a minimum of interiorsurface is exposed to the inclosed hot air for heat absorption andconsequent loss.

It will be noted that the plug is located at the extremity of a minoraxis of the shell 1, otherwise but one of the tubes 3 and 4t would beavailable for use.

While I have shown what I deem to be the preferred form of my inventionI do not wish to be limited thereto as there might be various changes inthe details of construc tion and arrangement of parts described withoutdeparting from my invention, and hence I desire to avail myself of suchchanges and alterations as fairly fall within the spirit and scope ofthe appended claims.

Having described my invention what I claim as new and desire to secureby Letters Patent is:

1. An electric curling iron heater comprising an oblate spheroidal shellhaving a projecting plug at the extremity of a minor axis thereof, aheating coil in said shell and connected with said plug, and a pluralityof different sized tubes arranged in said shell for the reception of theoperative portion of a curling iron and substantially coextensivetherewith, substantially as described.

2. An electric curling-iron heater comprising an oblate spheroidalshell, a heating coil in said shell, electrical connections for saidcoil, and a plurality of different sized tubes arranged in said shellfor the reception of the operative portion of a curlingiron, said tubesbeing obliquely disposed and passing each other adjacent the center ofsaid shell, substantially as described.

3. An electric curling-iron heater comprising an oblate spheroidal shellhaving a projecting plug at the extremity of a minor axis thereof, aheating coil in said shell and connected with said plug, a ')luralit ofdifferent sized tubes arranged in said shell for the reception of theoperative portion of a curling-iron, and a covering of asbestos for 5said shell, substantially as described.

4-. An electric curlingiron heater C0111- prising an oblate spheroidalshell having a plug at the extremity of a minor axis there of, a heatingcoil in said shell and connected with said plug, and a plurality ofdifferent sized tubes arranged in said shell for the rel t t 1 1 ceptionof the tongs of a curling-iron the major axis of said shell lying in ahorizontal plane and said tubes being inclined thereto, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
